Nevillehazeman's 600 watt OG Kush Single Plant SCROG

[nevillehazeman]

What's up everybody? This is my first grow diary and my first scrog ever. I'm a legal medical marijuana patient in Washington and the strain I will be documenting in this thread is a clone of OG Kush from Purple Cross in Seattle. That's as far as I know on the lineage, I hope it's a keeper!! Today my lady is finishing her 7th day of flower.

 

[nevillehazeman]

The OG kush is in day 7 of flower and under a 4ft by 4ft scrog. I made the scrog using 2" square kennel fencing stapled to a frame made by 2X4's. The pot she is in is a hamper that holds about 21 gallons of soil. To prevent soil falling out of the large holes throughout the hamper I lined the whole thing with a cut out section of replacement patio screen. I placed the ends of 2 air hoses into a large car wash sponge and placed that in the bottom of the hamper. The other ends of the hoses are attached to an aquarium air pump.

Everything looking good so far, I think....

 

[nevillehazeman]

Now down to business. Does anybody know wtf these spots could be that started appearing on the leaves?

 

[jm420]

shut off the hps when taking pics it will be easier to tell,but i'll go out on a limb and say its a calmag issue

 

[nevillehazeman]

Here are some new pics of the mystery leaf damage

 

[nevillehazeman]

Only a handful of leaves are starting to show this. The others seem unaffected.

I had the same problem last run, check the pH of your run off. As JM said could be cal mag, I feel that my last soil mix had too much dolomite lime in it and caused problems with all my plants last run, nothing major just burning on the leaves. I used less lime this time and clones of same plants, we'll see, so far so good.

 

[nevillehazeman]

The plant is potted in a weird mix. I bought a bag of Gardner & Bloome Harvest Supreme and a bag of Gardner & Bloom Potting Soil. I think it was the potting soil but it may have been the planting mix. I went home and laid down a big-ass tarp and dumped each bag out in two fat, separate lines. I had a bale of peat moss lying around so I crumbled a fat line of it down the middle of the two lines of soil. My dolomite lime has been sitting in the back yard for months getting rained on and is a mushy mess now. I scooped up several fat handfuls of this mess and threw it in the pile. I put maybe half a gallon of azomite in the pile also. I dumped between 3-5 gallons of perlite down the middle of the pile. Then I threw in a shovel full of soil from the ground and a shovel full of soil from last summer's raised tomato bed. I mixed the shit out of this for over an hour and bagged all of it back up. That's what I used to fill the hamper. My plant was in a gallon pot and was transplanted into the hamper and vegged for 3 weeks before being switched to 12/12.

Primary Uses:
An all purpose, pre-fertilized, planting and garden soil amendment. Formulated to provide abundant plant nutrients, improves physical characteristics, and balance pH when mixed with existing garden soil. Great as a nutrient top dressing and mulch.





The Gardner and Bloome Potting Soil, if that is indeed the other bag I bought, is described as:
A rich blend of Fir Bark Fines, Forest Humus, Canadian Sphagnum Peat Moss, Perlite, Worm Castings, Chicken Manure, Bat Guano, Kelp Meal, and pH balanced to 6.5 with both Oyster Shell & Dolomite.

Primary Uses:
*For use in all indoor and outdoor potting containers, or raised bed applications.
*May be mixed with existing garden soil to enhance conditions for planting.
*Mix with existing soil in containers or pots to improve soil nutrients and physical properties.

I don't have a pH meter but I'm planning on ordering one soon. Any suggestions? I'm looking to measure EC, ppm, tds as well. I took 2 gallons of water that I let sit for a day and I poured them into a 5 gallon bucket with 2 airstones weighed down at the bottom of the bucket attached at the other end to an aquarium pump. I added 2 teaspoons of molasses to the water and stirred it in until it dissolved. I added 2 fat teaspoons of kelp meal to the water and stirred it for a bit. I grabbed a handful of compost out of my worm bin and crumbled it into the water and stirred. I added a sprinkle of canna aktrivator trichoderma, as well as a sprinkle of advanced nutrients piranha and tarantula and stirred it in. I let it bubble up for about a day and about an hour before using I added a tablespoon of epsom salt. I gave about a gallon of this to my lady tonight. I poured some of the concoction into a sprayer and applied it as a foliar spray. I had it pumped up to a low pressure and had the nozzle on the coarsest setting to preent damaging the bacteria and fungi I was spraying onto the plant.

The spots are spreading. It kind of looks like Mg deficiency to me so I gave the plant epsom salts in todays feeding as I stated above. Shouldn't the leaves be a bit more yellow for Mg deficiency.
Check out this leaf from yesterday compared to today.

 

[nevillehazeman]

more damage

 

[nevillehazeman]

I thought the soil was drying out too much along the screen covered hamper holes since it gets so much air so I draped a towel around the hamper. The towel helps hold moisture in the air around the holes and now 2 days after introducing the towel, we have roots!!

 

[nevillehazeman]

The plant is still growing pretty well. I hope it will fill out the whole screen horizontally and then grow vertically with fat buds all throughout the screen. Does anybody have any idea what I might yield off this sucker? I'm hoping to get at least a P.

IMO you flipped to early so thats gonna effect max yeild,its also on your growing skills.Kushs are not typically known to be huge yeilders,so you got that going agaist you weight wise as well.You also have a deficiancy going into flower this dosnt help either.I grow DWC but I believe that plants grown in soil take a little longer to recover vs.DWC.
Theres alot of factors to consider when trying to pull an elbow off 1 plant with 1 light
My last run was 8 plants(medium Yeilders wich i feel the kushes fall into) 2 -400's scrogged with my eviorment pretty dialed in was about 600 grams.
With out knowing the exacts and with no insult intended I'll say around !/4 pound or less
Check out the soil grow forum some great info there as well as the infirmary.
Like I said I dont know your skills etc... and i grow totatly diffrent so dont take my opionons to heart .Good luck and I'll be lurking

most of this post exp[lains why ur having problems, i would try and strart over and throw a few more girls under the light and use proffesional grade horticulture products. The fact you are on Icmag is the best start to have cuz we are all here to help. imo a diff strain would be better for you and make your life a lot easier , again thats mho,

ok keep us udpated

That OG kush is a real mag eater, I have to say that the yellowing starting at the petiole(bottom of fan) and moving out is a slight def. of iron or P caused by too much moisture and not enough O2 in the roots. Soggy medium or cold temps will show the same signs of yellowing. The orange bronze buckshot pattern is usually cal/mag but whats causing it? not enough? PH lockout? You have a good foundation and seem to know whats up with regards to correcting it. Some may disagree but I would stay away from native(backyard) soil for fear of pathogens, disease and pests. I just re-read your first post and have to question the car wash sponge idea, there are hydro/soil hybrid systems like hempy buckets but IMHO soil and hydro should stay seperate.
The "true" OG can stretch 2x or more over about three weeks so be ready! Good looking grow and you should be able to hit close to a P. by the looks of it. After another week I would do some med. de-foliating to get more light to the interior bud sites. Nice work and I hope you resolve your slight issue asap. NS

TJO is right as rain. Quality medium=quality product. KISS

I got the car wash sponge idea from a grower on another site. He used what looked like a shopping basket you use instead of a cart at the store and he filled it with soil with a sponge in the middle acting like a giant air stone. I thought he had crazy good results so I thought I'd give it a shot. My plant was root bound and showing deficiencies so I had to pot her up or put her out. Even though the set up isn't how I'd like it yet I figured it'd be worth a shot to just flower the bitch and see what I end up with. I'm growing single monster plants under scrog so I will keep my plant numbers down and stay legal. I have a cutting of purple kool aid from hempluvr that I'll be throwing under a 4X4 scrog under a 600 watt hps next to this OG kush. I'll have more on that later as soon as I figure out what soil mixture I'm going to go with. My ultimate goal is to make my own soil mixture that's better than anything in a bag at stores.

jm420-
Thanks for the info and for following this thread. I hope I hit that P mark. The best I've done yet was about 500 grams off 24 plants under a 600 watt hps in a 4X4 area. Half were hashberry and half were white rhino and they were in gallon pots.

theJointedOne-
I would've rather used better soil but it was my only option at the time. I was thinking I might get lucky and find that next great cheap potting soil. Hopefully the epsom salts clear it up. I tried correct the fact that I have a crappy soil mix by top dressing about 2 inches of fresh worm castings and worms onto the top of the soil so every time I water juicy goodness will drip down to the roots.

I don't know what kind of OG Kush this is but I'm hoping it's the real deal since it came as a cutting from a Seattle dispensary. (Hopefully it ended up there from an old school grower who knows his sh*t) I read online that it is a stretchy bitch and will triple it's size before done. I heard the first few weeks of stretching are ridiculous. I've also heard it's more of a 9-10 week plant. With these factors to consider I decided to flip it to 12/12 when I did with the hopes that she'll fill out the screen in the first 2-3 weeks of stretching and then grow above the screen after that to form fat donkey dick buds everywhere.
